It seems likely that Spain will apply for and receive support from the ECB in time, but the funds that are currently available are unlikely to be enough to solve the country’s problems. Meeting Spain’s financing needs until the end of 2013 would cost about 200 billion euros and doing so until the end of 2014 would raise that to 300 billion euros.
